Hello, I am planning on doing a 4 inch lift to my 2011jk unlimited rubicon. I am very comfortable and confident doing these upgrades BUT I was wondering what everyone was doing about aligning the truck afterwards? Is it just a simple toe adjustment? Or will there be more involved (eg. camber/caster etc).
any advice would be appreciated.
thanks

 

The only real adjustment required is centering the steering. The lift does not affect the toe or caster. If you are going with a 4" are you changing driveshaft? 3-3.5 is usually the limit for stock shafts. When lifting that high I also assume you are changing out the stock control arms and track bars to adjustable one. With adjustable control arms you can adjust to get the most effective camber and pinion angle.

A 2.5 - 3" lift will allow you to run 35's with stock fenders or 37's with flat fenders and only a simple steering wheel recentering.

 

Theres a few things about alignments... alot of the times its just to make sure any changes are accurate (or your buying an awfully expensive set of tires, or fighting your jeep down the road)

the alignment though involves more than just centering the steering, your also making sure your axles are centered under the jeep, not offset (why bigger kits require replacement track bars, and adjustable trackbars)
and ofcourse centered steering wheel, caster of the axle for proper self centering (angle usually changes when the control arms are too long or to short, and proper camber on the tires and ofcourse a little bit of toe in.

if your replacing parts and not changing anything, you can get by with measuring how long a tie rod or drag link is, and installing the new link and setting it to the exact same measurement, but when you change a few parts, odds are something will be out of spec...

properly lifiting a vehicle is god awful expensive, cause your talking about making everything fit specific to your rig's weight, angles change and off the shelf kits just dont really work on a fully outfitted jeep... which is why you either have to take time and fabricate your own parts, or use adjustable parts and make them fit your rig properly

I do alignments...
